Remember that downgrading and installing custom firmware can be risky, and there is a chance of bricking your PSP if not done correctly. Make sure to follow these steps carefully and use trusted sources for the necessary files. Additionally, be aware that downgrading and installing custom firmware may void your warranty and may not be legal in all regions.
